Unable to set very low resolutions

Unable to set very low resolutions

[Ralph]

Hello,

Are there known issues setting very low resolutions?  I'm using
kernel 2.4.20 and the aty128fb driver, but from what I hear (or
rather don't hear) from other people it's not limited to that
driver.

The following is a working modeline for my card and my 15.75 kHz
monitor:

	modeline 320x240  6.04186  \
	         320 328 352 384  240 244 247 262  -hsync -vsync

I've converted that to the following fb.modes entry:

	mode "lowres"
        geometry 320 240 320 240 8
        timings 165511 32 8 15 4 24 3    
        hsync low
        vsync low
	endmode

But when I try to fbset this mode, I get this instead:

	mode "320x240-103"
	    # D: 10.410 MHz, H: 27.110 kHz, V: 103.471 Hz
	    geometry 320 240 320 240 8
	    timings 96061 14 26 15 4 24 3
	    accel true
	    rgba 8/0,8/0,8/0,0/0
	endmode

How so?  I really want to get this working and I'd be happy to
provide any information I can.

Ralph
